Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing porous alumina, which can more easily form a fine structure of the transcripting surface of a stamper. SOLUTION: This method for producing porous alumina comprises: preparing the transcripting surface formed of arranged microspheres 3 on a substrate 1 of the stamper; forming recesses on an aluminum alloy sheet by transcripting the shape of the transcripting surface; and anodizing an aluminum alloy sheet to obtain the porous alumina having micropores initiating from the recesses and intervals according to the recesses.
